The primary use case for extra perms is app-specific state directories, which may or may not exist (first run of any app).

Fortify state store instances was specific to aids due to outdated design decisions carried over from the ego rewrite. That no longer makes sense in the current application, so the interface now enables a single store object to manage all transient state.

This is no longer necessary as fortify no longer integrates with external user switchers.

The socket-based approach is no longer necessary as fsu allows extra files and sudo compatibility is no longer relevant.

Wayland is implemented as an Op to enforce dependency and cleanup, its implementation does not allow multiple instances on a single sys object, nor would doing that make any sense.

Had to pass the sync fd through sys. The rest are just part of a standard Op.

This value is used for passwd generation. Bad input can cause very confusing issues. This is not a security issue, however validation will improve user experience.

This removes the dependency on external user switchers like sudo/machinectl and decouples fortify user ids from the passwd database.

This option only changes mapped uid in the user namespace.

Also moved /dev/fortify to /fortify since it is impossible to create new directories in /dev from the init namespace and bind mounting its contents has undesirable side effects.

Chromium's D-Bus client implementation refuses to work when its getuid call returns a different value than what the D-Bus server is running as. The reason behind this is not fully understood, but this workaround is implemented to support chromium and electron apps. This is not used by default since it has many side effects that break many other programs, like SSH on NixOS.

This change moves all user switcher and shim management to the shim package and withholds output while shim is alive. This also eliminated all exit scenarios where revert is skipped.
